AbstractPrimary vascular tumours of the heart are rare and heterogeneous in their presentation and classification. We present a primary intramuscular vascular malformation of the left ventricle in an asymptomatic 12-year-old girl. Characteristics on cardiac magnetic resonance imaging, specifically increased signal intensity on T2-weighted images, and marked contrast enhancement with gadolinium were suggestive of increased vascularity. Histologically, the mass was determined to be an intramuscular vascular malformation of the small vessel arteriovenous subtype. This represents one of a select few intramuscular vascular malformations of the left ventricle reported in children. Our patient remains completely asymptomatic and has had no change in the size and appearance of the mass after more than 30 months of follow-up.

ABSTRACTCavernomas are vascular malformations which are collections of endothelium-lined sinusoids without intervening cerebral parenchyma. Hypothalamic location of cavernoma is extremely rare. We present a case of a 34-year-old male who presented with complaints of recent memory loss and vomiting. On magnetic resonance imaging with gradient sequences and contrast, a diagnosis of hypothalamic cavernoma was suggested. Excision of lesion was performed by a right parasagittal pericoronal craniotomy via transcallosal approach. Intraoperative findings and histopathology examination corroborated the diagnosis. The uniqueness of this case report is in the susceptibility-weighted sequence which led to the radiological diagnosis.

Abstract Stereotactic radiosurgery has been shown to treat successfully angiographically demonstrated arteriovenous malformations of the brain. Angiographic obliteration has represented cure and eliminated the risk of future hemorrhage. The role of radiosurgery in the treatment of angiographically occult vascular malformations (AOVMs) has been less well defined. In the initial 32 months of operation of the 201-source cobalt-60 gamma knife at the University of Pittsburgh, 24 patients meeting strict criteria for high-risk AOVMs were treated. Radiosurgery was used conservatively; each patient had sustained two or more hemorrhages and had a magnetic resonance imaging-defined AOVM located in a region of the brain where microsurgical removal was judged to pose an excessive risk. Venous angiomas were excluded by performance of high-resolution subtraction angiography in each patient. Fifteen malformations were in the medulla, pons, and/or mesencephalon, and 5 were located in the thalamus or basal ganglia. Follow-up ranged from 4 to 24 months. Nineteen patients either improved or remained clinically stable and did not hemorrhage again during the follow-up interval. One patient suffered another hemorrhage 7 months after radiosurgery. Five patients experienced temporary worsening of pre-existing neurological deficits that suggested delayed radiation injury. Magnetic resonance imaging demonstrated signal changes and edema surrounding the radiosurgical target. Dose-volume guidelines for avoiding complications were constructed. Our initial experience indicates that stereotactic radiosurgery can be performed safely in patients with small, well-circumscribed AOVMs located in deep, critical, or relatively inaccessible cerebral locations. Because cerebral angiography is not useful in following patients with AOVMs, long-term magnetic resonance imaging and clinical studies will be necessary to determine whether the natural history of such lesions is changed by radiosurgery.

Solitary Neurofibroma

Solitary neurofibroma of the heart is extremely unusual. Few reports of neurofibroma in the left ventricle have been published. In this case report, we present the results of transthoracic echocardiography, myocardial contrast echocardiography, cardiac magnetic resonance imaging, and histopathologic examination of a patient with a neurofibroma of the heart. The patient had no evidence of any other metastasis or primary tumor in other organs, which is clinically rare.

Chondroblastoma located in the talus is a rare incidence, and due to the weightbearing duty of the talus, the results of local excision may not be favorable. While the volume of the tumor increases, more sophisticated techniques may be undertaken. Cell-free matrix application for extensive osteochondral defects is gaining popularity for its structural support when it is used with microfracture and autograft application. In this case report, we present a patient with 13 × 20 × 8mm–sized chondroblastoma located in the talus. After evaluation of the mass, we performed curettage, iliac crest autograft application, and augmentation with cell-free matrix. After uneventful clinical follow up, we present our patient's postoperative second year magnetic resonance imaging and functional status.

Background and aims We explored the association between the total small vessel disease score obtained from baseline magnetic resonance imaging and subsequent cerebro-cardiovascular events in neurologically healthy Japanese adults. Methods The presence of small vessel disease features, including lacunae, cerebral microbleeds, white matter changes, and basal ganglia perivascular spaces on magnetic resonance imaging, was summed to obtain a “total small vessel disease score” (range, 0–4). After excluding participants with previous stroke or ischemic heart disease, intracranial artery stenosis (≥50%), or cerebral aneurysm (≥4 mm), a total of 1349 participants (mean age, 57.7 years; range, 22.8–85.0 years; 46.9% male) were classified into three groups by total small vessel disease score: 0 ( n = 984), 1 ( n = 269), and ≥2 ( n = 96). Cerebro-cardiovascular events (i.e., any stroke, transient ischemic attack, ischemic heart disease, acute heart failure, and aortic dissection) were defined as the primary end point. The hazard ratio (HR) of events during follow-up was calculated using Cox proportional hazards modeling with adjustments for age, sex, hypertension, diabetes mellitus, and smoking. Cumulative event-free rates were estimated using the Kaplan–Meier method. Results During follow-up (mean, 6.7 years), 35 cerebro-cardiovascular (16 cerebrovascular) events were identified. Higher small vessel disease score was associated with increased risk of cerebro-cardiovascular events (HR per unit increase, 2.17; 95% confidence interval, 1.36–3.46; P = 0.001). Events were more frequent among participants with higher score ( P < 0.001, log-rank test). Conclusions This study offered additional evidence for the clinical relevance of total small vessel disease score, suggesting the score as a promising tool to predict the risk of subsequent vascular events even in healthy populations.

Secondary paroxysmal dyskinesias (SPDs) are short, episodic, and recurrent movement disorders, classically related to multiple sclerosis (MS). Carbamazepine is effective, but with risk of adverse reactions. We identified 7 patients with SPD among 457 MS patients (1.53%). SPD occurred in face ( n = 1), leg ( n = 2), or arm +leg ( n = 4) several times during the day. Magnetic resonance imaging (MRI) showed new or enhancing lesions in thalamus ( n = 1), mesencephalic tegmentum ( n = 1), and cerebellar peduncles ( n = 5). Patients were treated with clonazepam and then acetazolamide ( n = 1), acetazolamide ( n = 5), or levetiracetam ( n = 1) with response within hours (acetazolamide) to days (levetiracetam). No recurrences or adverse events were reported after a median follow-up of 33 months.
